The Chevy Spark, one of our favorite little city cars, gets mean when fed with a 512 hp V8 from a Corvette Z06. Call it an insane modification, because frankly that is what it is. However, we're continually intrigued by efforts to give new small car bodies performance upgrades more fitting of a muscle car. Just think, if Aston Martin is toying with idea of a V12 in its Scion IQ-based Cygnet, could we also see a powerful miniature car from GM one day?
